Sure they will. We just won't find out about it. It's not wise to admit to the public that we can't control our airspace. I would expect them to find out how to capture one before an enemy does and then use the technology to our advantage. It would be a state secret.
The FedGov will never follow up on these, with the possible exception of a UFO landing on an aircraft and crushing it.
This Board finds "Pilot Error" to be the cause of this accident, the pilot of the Intergalactic Experimental aircraft exceeded the landing requirements of the spacecraft
and failed to follow proper proceedure at a major transit hub.
Case closed.
